Instructions
1. Print and cut out template
2. Trace template onto poster board / card stock
3. Cut out and decorate
4. Affix pennies to wing tips
5. Balance the nose of the bat on your finger, a pencil eraser, the corner of a table or a similar point
7. To learn more, try some of the experiments listed at the end of this post
6. Enjoy!

Tips
• Use your first card stock wing as a durable template for others
• Used cereal boxes work great
• Use painter’s tape to test different coin locations before permanently securing them
• Use hot glue or epoxy to secure pennies to wings

Experiments
• What effect does using a lighter coin have? What effect does using a heavier coin cause?
• How does the location of the coin affect the center of gravity?

We have found — contrary to our presupposition — that using a lighter weight cardstock allows the wings to sag down and forward, creating a more three-dimensional appearance, enhanced reality of flight (of flapping wings) and better balance!
